@EBikeBuilder_ and for the guys who want simplicity without the cost and complexity of some Vesc controllers they'll just have to hunt down an old version Bafang controller as long as they're still being sold.
Itll probably be locked down to the batteries bafang offers. I think the can bus SMILE batteries have a bafang BMS on them. That’s more tightly integrated where the controller and display can see the voltage of different cell groups from the BMS etc. The charging technology is probably better, etc. But with all that stuff being so tightly integrated, it might mean you are limited to the batteries that bafang will sell, with their BMS on it, that communicates with the rest of their systems. Probably need a special battery charger with special connector. Battery will hook to controller with some Can bus connector. I dont think it HAS to work that way, but it seems like that’s how bafang is going to attempt to make it work. Similar to bosch and etc. It’ll all work together and be sold as a kit most likely. With the BESST tool requiring bafang permission to access and use, seems they are moving away from rinky dink diy conversion kits business, and more towards “dealers”. But its been a multi year speculative rumor at this point. Only thing that makes it seem like its actually happening now is bafangusadirect closing down. If they hadnt shut down, i wouldnt have considered this newsworthy and it would have just been more of the same. But yeah it seems it might actually be happening at some point 😅😮
@@orbit5449 bafang has the 130bcd spider, But the chain line isnt very good with it. On my bike the 46T chainring is the biggest i can use that clears the chainstays. I went the single speed route and rearranged my cassette cog for a straight chain line
@@EBikeBuilder_ One big problem is it fits loose into the bottom bracket and can rock around, thats what loosens the lock ring as it chews up the metal . I used a shim out of a pop can aluminum and fixed that . Then jb welded a bracket to the top of the motor that clamps to the bike frame no problems. Ground off the teeth on that ring so it won't ruin the frame . The motor lifts UP under torque so just put a thin piece of hard rubber to protect the frame and have the motor tight up on it before tightening anything . Get rid of that slop in the bottom bracket is the most important . And please stop greasing the inside and out of the sealed bearings or they will spin in the housing or the shaft will spin inside . They should be a clean press fit .
UART is not a communication standard. If the controller receives bad bits, it may crash. CAN bus has a communication standard built in. Basically, the industry is moving away from "hacking" controllers to a more robust standard. Build more 1500W-2000W mid-drive motors!! :)
i'm sure many people were mislead by the business name, like Johnny suggested. Maybe bafang didn't like it either, and thats why they shut down. I think bafang is perhaps becoming more sensitive about its brand perception and who is selects to be dealers
It's not that big of a deal..It's just communication between battery Bms, motor and controller, with better computer control to program settings and such, depending on software, it could be worse, as in locked down....The new cable is adding a proprietary part for profit..I have CANbus cables for solar inverters and they are not shaped like that, they are the kind of connectors that you plug into a router, like the old telephone kind of connector..
The change to CAN BUS isnt necessarily bad, but it appears along with that change, bafang is making other changes which makes their stuff more tightly integrated. The 100$ BESST programming tool appears to require bafang approval and permission to login and access. Which is a bummer if you liked using the BBS02 and BBSHD with the Bafang displays and equipment. It seems like there are new proprietary connectors yes, ive never seen that orange charge port and connector shown on the battery. The battery seems like it will require a Bafang BMS which can communicate over CAN BUS with the rest of the equipment.
i've watched that video and thats been my experience as well, (from what i remember in the video) , is the battery cells brand is the most important factor. I've never had a samsung cell Pop off, they have some kind of current interrupt protection or something and foam stuff pops out the positive end. Whereas molicel doesn't have any protection etc. But yeah I have mixed feelings about UL Listing and UL Laboratories being appointed the sole arbiter of battery quality and testing. I dont like how one private company is in charge of all that < But UL has been around for a while its kind of our standard here I guess. Its good for the new york apartment building people. But like johnny said Im cool without UL listed stuff, it doesnt mean anything to me, im not putting an entire apartment building at risk
hey thats OK! i appreciate your support on UA-cam through your thoughtful comments and interaction! I think VESC can do canbus yes, and its not locked down!! another win for vesc
As long as the controller can be swapped out as easy as the current ones it doesn't bother me
yeah I dont think there is much to worry about from a DIY perspective , we can always rip that CAN BUS controller out, and do as we please 😇

The thing I'm waiting for is how locked down the battery options will be with the CANbus version.

Get one now before the tariff hits and the price goes up .
Awesome stuff. Keep on doing what you are doing
CANBus allows for much more Data from the controller and can then have programmable displays etc.
With nordlock washers and 60Nm torque on a steel bottom bracket shell it never gets loose.
Bbshd use 130 bcd chainring on stock adapter is good tip for change to 38T to 60T also you can use single gear to fix chain line.
60T good if you plan to go lightspeed.

Spend the $40 and get the M33 4 point socket to tighten the motor and it will never move.
oh, I'll find a way, Jump it onto a rock and it moves 😅 it also chews into the bottom bracket shell damaging the metal and paint. Its not great

Bafang USA Direct isn't the Bafang company, it was a retailer..Despite it's Orwellian name..And I think they had a questionable reputation..

I just received mine a week or two ago the bbso2 would it fall under this category?
as of now most systems are still UART , the CANbus stuff is very new. If your display has the circular green connector, it's UART

@@EBikeBuilder_ Yeah, I figured you've seen it. It was mostly for the benefit of the other visitors of the channel....
I can't afford to buy myself a coffee my friend. Sorry I can't support
Vesc allows for can communication, no problem

I think there's going to be cheap copies made of the programmer it's just going to take a little while.
